Type-2 blindsight is often characterised as involving a non-visual form of awareness that blindsight subjects experience under certain presentation conditions. This paper evaluates the claim that type-2 awareness is non-visual and the proposal that it is a cognitive form of awareness. It is argued that, contrary to the standard account, type-2 awareness is best characterised as visual both because it satisfies certain criteria for being visual and because it can accommodate facts about the phenomenon that the cognitive account cannot. The conclusion is made that type-2 blindsight is best characterised as involving a form of abnormal, degraded visual awareness.
二级盲视通常被描述为涉及一种非视觉形式的意识,即盲视患者在特定呈现条件下所体验到的意识。本文评估了关于二级意识是非视觉的这一说法,以及它是一种认知形式的意识这一提议。有人认为,与标准解释相反,二级意识最好被描述为视觉的,这既是因为它满足了视觉的某些标准,也是因为它能够解释认知解释所无法解释的有关该现象的事实。得出的结论是,二级盲视最好被描述为涉及一种异常的、退化的视觉意识形式。
